Marcus Mariota is visiting the Tampa Bay Buccaneers for the first time today, giving the team a chance to get to know the Oregon prospect in person. The team will work him out privately next month as well, presumably trying to assess how well he'll transition to a pro-style offense.
As the Bucs did with Jameis Winston, they're publicizing this visit with some great photos. We'll probably see some video footage at some point, as well. This is all part of the Bucs' push to expand their online presence, and get more interesting stuff out there for the fans, something they've been actively doing since a few months before Lovie Smith was made the head coach. It's no real indication of who they favor in the draft.
Speaking of Winston, the FSU quarterback won't be attending the NFL Draft in Chicago in person, according to The MMQB. That means no footage of him hugging the commissioner or otherwise being lavished by the media. But that's probably for the best, given the scrutiny he has been and will be under.
